With a small footprint, no electrical requirements and no moving parts the HeadCell

Weedscreen Cleaners from Aquatic Control Engineering are automated systems for removal of debris, vegetation, and floating waste from water intake screens. Units use grab or rake mechanisms to lift debris and deposit it into a skip or dump area. Payload options range from 210kg to 1500kg. Systems are custom designed for each site and can be

Robust, high-quality Micro Screens are a cost-effective and efficient way of continuously reducing levels of fine, suspended solids and phosphorous across a broad range of trade effluent and municipal wastewater treatment applications. They can be supplied as a new, stand-alone tertiary treatment solution or they can be fully integrated within an

Althon pipe-mounted vermin grilles are manufactured in grade 304 stainless steel. These vermin grilles for pipes are hinged to allow passage in the direction of flow but will prevent rats and other vermin climbing up the pipe. Anti-rodent pipe-mounted gratings are fixed into the pipe. The standard range is available for pipework from 300–600mm

Multiflo™ clarifiers with lamella settlers are used for the clarification and polishing of water and the treatment of wastewater. Systems are compact and flexible, and can be used in small- to large-sized plants to treat any kind of water characteristics and pollutant loads. Multiflo™ Softening and Multiflo™ Carb can be used for softening and polishing to a high water quality

The iHB integrated lamella clarifier has been designed and developed as an all-in-one treatment system with integrated chemical reaction tank and hopper bottom settlement tank. It provides a reduced footprint and cost compared to the use of individual items, and also reduces installation time on site

Remove, separate, classify and wash wastewater and process solids at a range of municipal and industrial treatment plants. The TeaCup® is a high-performance accelerated gravity grit removal system that has been the benchmark for high-performance headworks grit management since 1976. Optimised for grit collection, grit washing, sediment removal on

Colloide uses lamella settlers within its lamella clarifier systems, which greatly increases the clarifier capacity and enables a much greater flow to be treated in the same footprint as conventional clarification. Their design also ensures maximum efficiency in terms of upward flow velocities. The lamella settlers can be used in new builds and

Siltbuster Lamella Settlement Tanks are mobile settlement units designed for continuous removal of suspended solids from water, using inclined lamella plates to maximise settlement area within a compact footprint. Units are made for rapid deployment, require no power, and can be linked for higher flow rates. Suitable for construction, industrial

Screen CSO flows in a small footprint, maintaining high treatment efficiency even under surcharged and submerged conditions. With the threat of a sewer overflow, you need a powerful and highly efficient screen that will keep flow moving while maintaining high treatment. The Heliscreen® is a compact, powered combined sewer overflow (CSO), sanitary

Back Raking Machines are self-contained units for debris removal at pumping stations and drainage systems. Compact design allows installation in small or retrofit sites. Chain-driven rake lifts debris up a built-in trash screen and deposits it away from the intake. Optional conveyor system moves waste directly to a skip for easy disposal

Aquatreat's static channel screens and sieves provide continuous solids and liquid separation with no power requirement and virtually no maintenance. They are simple prefabricated units with screen and sieve spacing to provide separation for a wide range of applications. All screens and meshes are made of stainless steel, providing long and

Bridge Scraper Systems delivered by Colloide are produced with expert knowledge and design skills to meet bespoke requirements. The off site design and build is a cost effective solution, allowing Colloide to assemble and test equipment in a controlled environment minimising foreseeable problems onsite, costs and time. Circular and rectangular

Grit Decanter is a non-mechanical dewatering system designed to retain fine wastewater or industrial process grit with little water content, allowing for cost-effective disposal. An economical alternative to conventional dewatering systems, it is custom-designed to match local disposal truck configurations and is ideal for smaller treatment plants

Compact, battery-operated, easily transportable and effective solution for treating high pH, sediment-laden blast water from lance-cutting hydrodemolition operations. Ideal for use on roadworks or on schemes where access is limited, such as multi-storey car parks, basements, etc. Can operate continuously at flowrates of up to 5m3/hr and be powered

Hydro MicroScreen™ is a low-energy, small-footprint rotating belt screen that delivers exceptional solids removal from industry process water and wastewater. Maintaining efficiency even at peak design flow rates, it enables industrial and municipal operators to meet discharge requirements, increase efficiency and save money by cutting energy and

The Hydro-Industrial externally-fed rotary drum screen reliably and effectively separates screenings from industrial wastewater prior to further treatment. The compact nature of the system ensures effective screening in a small footprint (as little as 0.9m2 / 9.6ft2), particularly for effluent containing high concentrations of fats and oils, and a

Screen gross solids and floatables at CSO sites with infrequent overflows. Though overflows may be infrequent, when they occur they are still damaging to the environment.
