WeirWasher Automated Cleaning System are engineered to the specific design parameters of each tank .WeirWasher Automated Cleaning Systems are ' ONLY technology that is SCADA/PLCATIMI automated. WeirWasher. ACS removes the algae, scum, grease, and other debris that grow. build up on weirs, troughs, baffles and oth. using rotational spray.WeirWasher ACS removes Grease Wax, Polymers, Resins. Pulp, Fibers and other sticky materials from the weirs, trough and other surfaces. The spray apparatus does not contact the surface so it will not clog with the material beina removed.

WeirWasher, ACS model WWR uses the in plant service water of nominally 65 psig at 15 to 45 gpm depending upon surface area covered. Water is supplied to piping that runs under the walkway out to the center column. The piping then enters the center of the column running through the center of the drive unit. The piping proceeds down the middle of the center column and out the square holes in piping for the mixed liquor effluent. The pipng proceeds down the outside of the column to the location of the WeirWasher, ACS center unit. The pipe is then connected to the center stationary unit, which allows the water to enter the center unit. The water flows between the stationary and rotating components of the center unit. The piping is then connected to the rotating component of the center unit. The clarifier drive unit drives the center unit with the rest of the rotating structure. The piping is then routed along the scum arm or along the bottom structure of the rotating structure of the tank or clarifier. The piping then is connected to the spray apparatus, which sprays the areas needing cleaning. The areas that can be cleaned are as follows:

  • Scum Ring (Inside and outside)
  • Weir (Inside and Outside)
  • Launder (overflow, sidewall, bottom)
  • Outer wall (center mounted launder designs)

The center unit during operation is designed to have a small amount of leakage. This leakage allows the center unit to ride on a small water film between the stationary and rotating components of the center unit minimizing the horsepower necessary to rotate the rotating component of the center unit.

Improve safety, reduce maintenance costs, and optimize treatment equipment operation with automation! Grease, Algae, Debris, Scum, Foam, Sludge and other materials can accumulate, diminishing equipment function and requiring regular cleaning maintenance that is both time consuming and hazardous. Automated Cleaning and Control Systems can address the collection areas of the unwanted material with the use of water. These debris control methods use less water and energy, require less maintenance time, and do not use chemicals.

WeirWasher Automated Cleaning Systems remove the algae, scum, grease and other material from the weirs and other surfaces on clarifiers, thickeners and other tanks. WeirWasher, ACS uses plant non-potable water to clean irregular and porous surfaces, bolts and any other irregularities. We have systems for square and irregular applications as well. WeirWasher, ACS designs have been in service for over 7 years. Our nozzles are in use in many industrial applications and have proven to be the best available. WeirWasher, ACS can clean surfaces under the water level up to one foot under water. Request a copy of a study being conducted to determine the effectiveness of this system and the direct effect to UV chamber fouling.

Eco-Blaster, Biological Control Systems address a wide range of material control concerns including foam, scum, grease, algae, sludge, paper, pulp, rags, sand, stones, or other undesirable material automatically without the use of chemicals. Applications include aeration basins, clarifiers, head works, feed wells, screens, EQ basins, wet wells, gravity belt thickeners, etc. Screens, for instance, require a simple retrofit of the existing sprayer or brush with effective results for a minimal investment . The cost savings for foam applications are significant when compared to the cost of de-foaming chemicals. Significantly reduce the maintenance time, costs, and chemical requirements while improving the cake production of a gravity belt thickener. Grease accumulation will lead to odor concerns, degredation of the the tank walls, probes, ladders and other components and can pose hazards for staff to remove. Utilization of an automated system will prevent this accumulation, including the thick mats of grease. Moderate foaming can become problematic in the anearobic zone of aeration basins when the foam amasses and thickens. Pest infestations, odor problems and cleaning concerns are easily eliminated with an Eco-Blaster design.

Weir Shield Odor and Light Control Systems are comprised of aluminum laminate panels with a co polymer core applied to clarifier launders to prevent algae growth or as current density baffles.

Here are some of the features of WeirWasher, ACS:

  • IMPROVE SAFETY
    • Significantly reduces time in or near the treatment equipment performing cleaning maintenance
    • Reduce algae fouling and cleaning in sand filters, UV disinfection, chlorine contact tank
    • Spray penetrates 4-10 inches below water line to clean inaccessible/dangerous clarifier designs
  • PERFECT RETRO FIT
    • ALL CLARIFIER DESIGNS (square, rectangle, round)
    • Maximum design flexibility
    • NO costly tank changes such as bolt head removal, baffle bracket replacement or walkway support removal
    • Articulate around obstructions-walkway supports, dual troughs, multi sided launders
  • NON CONTACT CLEANING
    • Significantly reduces possibility of becoming caught on tank components
    • Excellent choice for primary clarifiers, thickeners and tanks with grease accumulation
    • Light Weight Design - no counterweights need
  • GREEN TECHNOLOGY
    • Minimal water usage compared to fire hose method
    • Narrow cleaning stream and rotation-maximize the available pressure for effective material removal
    • ELIMINATE need for chemical usage to control algae
    • WATER is an EFFECTIVE CLEANER even at lower pressures- no need for brushes or scrapers
    • Small carbon foot print-few replacement parts
  • DYNAMIC SYSTEM
    • Algae control system can change with the facility capacity
    • Maximize results with the addition of a booster pump as flows increase
    • Sludge and debris accumulating on surface will be driven back into solution
    • Feed well sprayer for foam and sludge accumulation control
  • PROTECT UV INVESTMENT
    • Prohibits large algae bloom growth that can break off and foul the UV chamber and require removal
    • Large algal blooms can reduce UV effectiveness or cause bulb breakage
  • SIMPLE TO OPERATE-TRULY AUTOMATED
    • Controlled directly by SCADA or automatic valve--No manual engagement or disengagement with a hook required
    • Uses available non-potable plant water
    • System drains when off so *No Freezing*
    • Clarifier bottom cleaning attachment--pre clean tank before entering
    • Few Moving Parts=less maintenance
  • LOWERS TSS
    • Water spray cleans past brackets, walls, etc. to provide effective and consistent algae control
    • Water spray penetrates 4-10 inches below water surface
    • Consistent daily cleaning
    • Cleans irregular and porous surfaces
    • Minimize UV chamber fouling
  • PERFORMANCE ENHANCING
    • Optimizes clarifier/thickener performance by allowing consistent flow through weirs preventing short circuiting and preventing solids collection in the influent trough
