Grit Snail® quiescent dewatering belt escalator
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
TeaCup® grit removal system
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
SlurryCup - grit washing, separation and classification
SlurryCup™ is a grit washing system that uses two levels of separation and classification to capture, wash and classify grit as small as 75µm from grit slurries, primary and secondary sludge, protecting downstream processes from abrasive wear and clogging. The SlurryCup™ is extremely effective at washing grit captured at the preliminary treatment
Grit King® grit separation for wastewater treatment
Grit King® is a compact, unpowered advanced grit management system that removes fine grit to protect downstream processes at small, medium or large wastewater treatment plants. Removes 95% of 106 µm particles or larger, preventing costly downstream grit abrasion and deposition. With no moving parts, requiring less than 150mm of headloss at average
SpiraSnail® grit dewatering system
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
J+A CIS™ combined inlet system
The J+A CIS™ combined inlet system is a high-efficiency screening and grit removal system. It uses the most up-to-date methods available for the pre-treatment of raw sewage effluent, resulting in lower head loss. Suitable for all sizes of treatment works, it has a small footprint and is ideal for small plants. Specification: CIS (J+A Design) up to
J+A screw classifier
J+A Screw Classifier systems are free-standing units that are used for the separation of mineral grit from other types of solids. They provide dewatering of grit from grit collection systems, separation of organics from collected grit and reduction of the pumped water volume to the classifier through the use of grit cyclones. The screw classifier
J+A Crossflow™ Detritor grit removal
The J+A Crossflow™ Detritor grit trap consists of a rotating grit-collecting mechanism and a reciprocating rake grit-cleaning mechanism. It is designed to remove 95% of grit at 2.65 specific gravity and produces a substantially grit-free liquid and a cleaned, well-washed, drained grit. Benefits include: Continuous operation Minimum maintenance
J+A Jeta® grit trap
The J+A Jeta® grit trap provides a high level grit removal within a minimal footprint. It takes full advantage of gravitational settlement, and is highly efficient. With a simple, slow-rotating mechanism, it also uses minimal energy. Specification: Capacity (l/s) up to 3000 Diameter (m) 1.8 – 7.3 Grit removal efficiency 95% of 0.2mm particles at
