Primary wastewater screening

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

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

Althon flange-mounted vermin grilles are designed to fit between two flanged pipes or fittings, or at the end of a flanged pipe run: prevents rodents and other vermin entering connecting pipework; available in sizes to fit 100–450mm PN16 flanges; can be manufactured to suit any pipe size on request; made from stainless steel

Get efficient, economical grit dewatering at smaller plants with no washwater requirements. The SpiraSnail® is a highly efficient screw-type grit dewatering system that delivers 95% removal of all particles 106 µm and larger and 75% of 75-106 µm particles to cut solids handling and disposal costs. Designed to work in combination with a Hydro

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

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

Automated rotary screens separate solids from liquids using a rotating filter drum made from stainless steel grate or perforated mesh. Screen apertures range from 0.15 to 6mm, allowing for coarse or fine screening. Continuous rotation for automated solids removal. Self-cleaning action using process fluid

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. The Hydro-Static® Screen offers an economically sustainable screen for combined sewer overflow sites with infrequent overflows, but at which environmental protection is still a

Struvia™ phosphorus recovery system recovers and reuses phosphorus from wastewater and concentrated industrial water. Converts phosphorus in effluent into struvite crystals for use in fertilisers and animal feed. Reduces reliance on mined phosphorus and helps manage sludge disposal and maintenance costs: recovers phosphorus from municipal

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

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

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

Get superior non-turbulent grit dewatering, optimised for fine wastewater grit. The Grit Snail® is a quiescent dewatering belt escalator that captures and dewaters the fine grit output from a HeadCell® or TeaCup® grit removal system. Providing solids output with low water content, the Grit Snail® reduces solids handling and landfill costs

Actiflo™ is a compact, high-performance clarifier used for the treatment of water and municipal and industrial wastewater. It can eliminate up to > 99% turbidity, suspended solids and associated pollutants. Characterised by very short hydraulic residence time and high process stability, the process is fully automated and requires minimum maintenance

Remove more, finer grit to protect downstream equipment, increase plant efficiency and cut maintenance and repair costs. The HeadCell® is a stacked tray grit, sand and solids separator that captures and retains 95% of all grit 75 µm and larger - guaranteed. With a small footprint, no electrical requirements and no moving parts the HeadCell
