This fact also ensures that all models of belt press units are totally enclosed creating work areas which are clean, dry, odour free with low noise levels.

The Gravity Belt thickening range varies from small to large applications where floor space is premium. As with all our ranges, Gravity Belt Thickening systems can be supplied as fully integrated packages.

A turnkey system from Seven Hills International Limited includes a belt filter / thickener, polymer preparation system, sludge handling system and control system.

Additional high performance elements include the Sludge Expert system for automated process optimisation and the Dual-Mode feature for maximum flexibility with final cake dryness. Seven Hills designs and manufactures all system components, ensuring that all elements of the system work in harmony.

A turnkey system guarantees maximum sludge conditioning, maximum filtration, maximum cake dryness and maximum ease of operation and maintenance.

• Single belt system for smaller capacity bio solids dewatering or thickening applications
• Flexible, high performance thickening systems
• Stainless Steel
• Cost effective alternative
• Higher dry solids content
• The dry solids content of the thickened bio solids may be set by site personnel to suit specific requirements

Series Alpha 10000 has evolved from the very successful series 1, sludge press range which, over the year has set the standard for simple reliable dewatering of extended aeration bio solids.

There are Series Alpha 10000 belt units for both Dewatering and Thickening applications.

The Dewatering units are particularly suitable for the smaller site where the savings on capitals cost far outweigh the additional disposal cost of a slightly greater volume of bio solids cake.

The Thickening units, complete with patented dual mode facility have all the features and application flexibility of the larger series Alpha 40000 range. They provide an exceptionally cost effective method of bio solids thickening when long daily working hours are permitted.

The dry content of the thickened bio solids may be set by site personnel to suit the site specific requirement.

Both Dewatering and Thickening systems are available either as fully integrated skid packages complete with all pumps. Polymer systems, controls etc. or separate components.

Series Alpha 40000 series of gravity belt thickeners have evolved to meet stringent bio solids thickening standards.

In addition to gravity thickening bio solids in the traditional manner series Alpha 40000 thickness may be fitted with the patented dual mode system. This presses a selected proportion of the bio solids load and allows the dry solids content of the thickened bio solids to be simply adjusted (typically in the range 5% to 10 %) to meet specific requirements.

“Double Deck “models are available which makes best use of floor space for large capacity machines.

The complementary Series Alpha 10000 series is especially suited to medium and smaller capacity systems
