Trident TNZ LLC. products

The Trident MD Press excels where conventional screw press dewatering units are limited by their design. Ineffective dehydration or increased maintenance are challenges that operators are too familiar with. The key to the efficient MD Press dewatering process is its dewatering cylinder. This cylinder can achieve thickening and pressing (dewatering) in a single integrated operation. The MD Press can accept a wide range of sludge types, from very dilute sludge with less than 0.5% solids to pre-thickened sludge. Separate thickening, storage and conditioning processes are eliminated. In addition, required operator attendance, power consumption and water use for operational wash-down are significantly reduced. 

The Trident polymer hydration unit is an automated two stage polymer make-down and aging system that accurately mixes, ages and dispenses hydrated polymers for use in wastewater treatment. In the make-down stage precise amounts of polymer are metered onto a diffuser plate, liquefied and thoroughly mixed. The blended polymer solution is transferred by gravity from the make- down and aging tank to the second stage tank for introduction to the waste stream. The hydrated polymer is injected into the waste stream via a positive displacement pump that delivers exact amounts of polymer for cost effective and efficient applications. Depending on the project requirements Trident can provide a polymer system for both dry and emulsion polymer. 

The Trident Screw Press is a durable, robust and efficient piece of equipment, purpose built for making bedding material from dairy manure. The press features a screw with interrupted flighting, graduated pitch and resistor teeth. The flighting is notched and a 1/32 inch screw-screen clearance further promotes effective dewatering and low maintenance operation. The screw shaft is supported on both ends ensuring robust and low wear operation. A simple yet effective shaft seal design prevents machine failure from manure liquid entering the gearbox. An air operated outlet door allows automated output control. The produced solids are coarse and fluffy with up to 34% dry matter, providing both cow comfort and excellent drainage characteristics required for use in today’s modern dairies. The equipment with its robust construction and corrosion resistant components is designed for long lasting operation, while reducing maintenance and operational costs.

The Trident Shaftless Screw Conveyor is a great addition to the Trident dewatering equipment and is used for the disposal and conveyance of dewatered sludge from municipal wastewater treatment processes, residential sewage pretreatment plants, or livestock waste applications such as manure processing systems. An optional electrical control panel or integration into the plant’s automation is available.

Trident offers the option to provide centrifuge equipment for manure separation on dairy farms. A centrifuge can be a good way to improve on-farm nutrient management. The equipment is recommended as secondary treatment step for manure liquid (effluent) from primary separators such as rotary screens or screw presses. After the initial primary treatment the effluent still contains large amounts of fine solids and high nutrient levels, which can be problematic for lagoon storage or NMP requirements. The centrifuge is capable of concentrating these fine solids to a cake material, usually with 15-25% TS. The produced effluent (centrate) is low in solids and nutrients, benefitting downstream processes on the farm. By eliminating a large portion of the solids going to longterm storage, the farm is able to realize substantial cost savings by reducing expensive lagoon clean outs.
