Key Operational Questions

Do you have only one pressure and vacuum vent and flame arrester on cover?

• We recommend the 97190 Safety Selector Valve with Dual Units for Maintenance

How often do you clean their flame arresters?

• Should be annually. If they have old units, suggest new Shand & Jurs 94306.
• If they have Square units with trays, Spiral units are the same functionally. Lead time is 2 weeks typically.

Do your pressure and vacuum vents leak?

• • If so, we suggest to replace the seals with S&J 94020 with Expanda-Seal (Best Seal on Market)
  • 

Do you have a cold weather application?

We recommend  an All-Weather Teflon Coating and Insulation Jackets  which are available.

You wouldn’t spend any time outside without bundling up and neither should your safety devices. Fit them with Insulation Jackets from Shand & Jurs Biogas during these cold winter months to maximize your heat source and help keep condensation vapor from freezing them up which could cause damage. Our Insulation Jackets are constructed of a silicone impregnated woven glass cloth lining with a 1 inch thick 6 lb. density fiber glass insulating material. Through cover quilting pins, provide support to keep the insulation from shifting inside while providing dimensional stability ensuring uniform heat retention. Velcro cinch belts and straps with D-rings allow easy install/removal and maintenance access to tube banks when necessary without removing the entire jacket.

Park Process – manufacturers dewatering containers, with a porous bottom to dewater sludge, grit or other fluid. The dewatered portion is collected to a drain. The false bottom can be permanent with stainless steel wedge bottom of various openings or with a disposable needle punched polypropylene geotextile filter. The most common type of dewatering container is based on a roll-off box design, although any type of container that is water tight can be made into a dewatering box. This includes containers that are commonly referred to as self-dumping hoppers and front loaders. Park Process manufacturers industrial filtration, Oil-Water Separators, batch and inline polymer make-up systems, eductors,  mud cleaners, and oil field mud hoppers.

JCI represents packaged water treatment plants as manufactured by AWC Water Solutions.

AWC Water Solutions  (formerly Corix) manufacturers complete packaged and modular water treatment systems designed to meet a variety of flow and water quality parameters, producing from 10 to 5,000 gpm of clean water for both potable and industrial. Systems conventional, membrane-based systems, or combined hybrid systems for optimal life cycle costs. Our water treatment offering includes:Direct filtration (DF), Adsorption clarification (AC), Tube settler (ST), Dissolved air flotation (DAF), Membrane filtration – ultrafiltration (UF), nanofiltration (NF)
reverse osmosis (RO) and Pressure filters (PF) with the following advantages:

• Corrosion-Resistant: Our plants are fabricated with marine-grade aluminum alloys and stainless steel to provide superior resistance to chemicals and corrosion, resulting in longer life
• Cost-Effective: Plants are pre-assembled and pre-tested in our controlled facility, often saving 50 percent or more over in-situ construction. They can also be integrated into pre engineered building systems for increased savings and reduced schedule.
• Redundancy and control system capabilities: provides set-point optimization needed to ensure quality goals are continuously met while minimizing operating costs with remote sensing, data logging and remote communication capabilities to enable operators to review and attend the unit as needed either from a distance or on site

Treatment Technology Based on Contaminant

Direct filtration (DF)

Adsorption clarification (AC)

These plants are ideally suited for stable ground or surface waters where turbidity levels seldom exceed 30 NTU that are designed using a combination of hydraulic “tortuous path” flocculation/clarification filtration and rapid rate filtration to produce potable water with superior quality.

Each train treats capacities up to 2,800 gpm (2 MGD)  where multiple trains can be combined for higher flows to  reliably achieve less than 0.1 NTU turbidity and 2.5-log, multi-barrier protection against Giardia and Cryptosporidium. Options for increased iron, manganese and arsenic removal.

• Flash mixing: A coagulant added to the raw water precipitates dissolved contaminants and encourages suspended particles to form “flocs” with multi-chemical injection ports for coagulant, polymer, pH adjustment to provide process flexibility
• Flocculation: As the water passes upward through the upflow clarifier filter, the flocs grow and are partially removed by the coarse media. Acts as both flocculator and clarification zone to reduce filter loading
• Filtration: high-rate media filter removes remaining particles. Solids that accumulate within both the upflow and downflow filters are periodically removed by automatically controlled air/water backwashing.
  • Mono, dual and multi-media options
  • Air scour/water backwash option for reduced water consumption and improved cleaning
  • Optional water backwash with surface wash
  • Nozzle and plenum-type underdrain

Tube settler (ST)

Packaged Tube Settler (ST) process use proven technologies to produce clear, safe drinking water from low quality sources. Capable of purifying the most difficult types of raw water, our ST plants are particularly suited for surface waters with high and variable contaminant excelling in treating cold water and very high levels of turbidity, iron and manganese.

Each train  treats capacities up to 800 gpm (multiple trains can be combined for higher flows) and reliably achieve less than 0.1 NTU turbidity and 2.5-log, multi-barrier protection against Giardia and Cryptosporidium.

Clarification portion’s accumulated solids are removed hydraulically from the clarifier bottom and the clarified water passes on to the filter for final polishing utilizing:

• Inlet/outlet manifolds for even flow distribution,
• 60° rigid plastic settling tube modules,
• “V” hopper bottom for sludge thickening and hydraulic sludge removal,
• Sludge blanket sample and location ports,
• Flat bottom, mechanical sludge removal option available

Dissolved air flotation (DAF)

Packaged DAF water treatment plant treating lake and reservoir water containing high levels of color, algae and turbidity, as well as cold waters and high levels of iron and manganese.

Each train treats up to 1,400 gpm (multiple trains can be combined for higher flows) and reliably achieve less than 0.1 NTU turbidity and 2.5-log, multi-barrier protection against Giardia and Cryptosporidium.

DAF: Microscopic air bubbles are injected in the flotation zone. The 50 micron bubbles used for flotation are formed by recycling a small stream of clarified water through an air pressurized, packed tower saturator to specially designed nozzles at the DAF cell inlet. Here, a rapid pressure drop causes the air to come out of the solution and form millions of small bubbles, which are then dispersed through the flocculated raw water. Then, the bubbles rapidly float the flocs to the surface and the accumulated float is skimmed off.

• Inlet/outlet manifolds for even flow distribution
• Mechanical float or hydraulic removal options are available
• “V” hopper bottom for sludge thickening and hydraulic sludge removal option available

Direct Filtration

Packaged water treatment plants based on direct filtration (DF) technology using a combination of hydraulic or mechanical flocculation and rapid rate filtration to provide superior quality to potable water. They are ideal for stable ground or surface waters where turbidity levels seldom exceed 10 NTU.

Each train treats to 1,500 gpm (multiple trains can be combined for higher flows) and reliably achieve less than 0.1 NTU turbidity and 2-log protection against Giardia and Cryptosporidium.

Pressure filters large particulate matter is captured by coarser, lighter media near the top of the filter bed. Smaller particles continue down to the successive lower media levels, where the spaces between these finer media capture the particles down to 10 microns. This multi-media filter allows a pressure drop build up across each media section, thereby utilizing the full bed depth for filtration of all particle sizes.

The AWC filter operation is fully automatic and requires no separate source of backwash water. The filter will backwash when a preset (usually 10 – 12 psi) differential pressure drop is sensed across the filter inlet to outlet. Backwash may also be initiated by setting the built-in time clock. On a duplex or triplex system, an interlock allows continued filter operation beyond the backwash initiation signal, if another filter is in backwash. When a backwashing filter comes into service, the dirty filter will automatically backwash. Incidentally, the same interlock feature is supplied on softeners for regeneration sequencing. Upon backwash, raw, unfiltered water is directed upward through the filter at approximately 15 USGPM/Ft2 for 10 minutes, expanding the media. This also scours and separates the dirt particles which exist in the backwash water to drain. The backwash is automatically maintained at a fixed factory set flow rate, regardless of influent water pressures which may range from 20 to 100 PSIG. The filter media is contained in the tank by having a properly engineered freeboard height.

• Pressure tank(s) shall be welded steel construction with support legs, conforming to ASME Code.
  • Designed for 100 psi working pressure and tested to 150 psi.There shall be adequate side height to allow 50 percent bed expansion during backwash. It shall have provision for media loading through an 18″ x 24″ manhole in the top head.
  • The upper influent supply shall have a baffle plate or be directed to evenly distribute the flow over the media bed.
  • The lower collector shall be a reinforced steel distributor plate welded around complete circumference with horizontally discharging Stainless Steel nozzles spaced on 6″ centers.
• Automatic Control System Includes: Control Panel, Five Butterfly/Ball Valves with Electric/Pneumatic control for service, backwash and rapid rinse. The backwash valve is equipped with an adjustable flow limiting control.

JCI is furnishing launder covers  as manufactured by Protectolite for a local project. Call us at 816-525-3320 for the following FRP clarifier components needs for weirs, scum baffles, flat covers,  Stamford baffles, and clarifier launder covers:

Protectolite manufactures, designs, and furnishes custom fabricated FRP clarifier parts for the water and wastewater industry. Protectolite™ is an approved and preferred supplier of fiberglass components to a number of the top Consulting Engineering firms in North America. and has furnished FRP products such as Scum Baffles, Stamford Baffles, launder covers, and clarifier covers to waste water treatment plants across the USA for the past 20 years.

Launder Covers

Protectolite listened to their customers and designed the cover to simply maintenance and operations with the ease of opening a design that is curved to be stronger and make it lighter to lift while providing a tighter cover to keep the sunlight from striking the weirs and baffles to prevent the formation of algae. Without sunlight, algae is eliminated along with the constant maintenance of cleaning and issues with downstream structures such as UV or filters.

The covers are custom designed to open to the center of tank, perimeter or side of the tank.  The most popular design with the operators in mind is for the cover to open away from the operator where they has full access to the weir and troughs.

Weirs, Baffles, Troughs and Stop-Logs/Stop Plates

FRP  composites make weirs, baffles and troughs the ideal choice for use in water and wastewater applications.

• • Excellent corrosion resistance
  • High strength
  • Lightweight and easy to install
  • Longevity in all climates
  • Low maintenance

Density Current Baffles / “Stamford” Baffles  

Density Current Baffles improve clarifier flow performance by redirecting  these currents back toward the center of the tank. This prevents these currents from short-circuiting and carrying light solids into the effluent reducing clarifier total suspended solids (TSS) and increasing the hydraulic capacity of the clarifier.

• Custom designed baffle sections fit any tank configuration
• Lightweight and modular for easy installation and maintenance
• Separate FRP support brackets for ease of installation
