Sludge sampler

The AMS Multi-Stage Sampler can be used to collect sludge samples up to 4 feet in thickness. The sampler has four stainless steel x 12" sampler body sections (a base section and three sampler body extension sections) to allow field personnel to make a sampler to the length that is needed. The kit comes with three 4 foot SS extensions that allow users to deploy the sampler through 12 feet of water before reaching the sediment. Dredges may also be used to collect samples from the top 4" of the sludge. The Ekman Dredge is used for sampling benthic communities inhabiting soft bottomed aquatic environments. AMS Inc.

Sludge blanket monitoring

Krohne's new Optisys SLM 2080 optical sludge blanket measurement system offers accurate measurement of sludge blanket depth, separation zone, and swirled solids (fluff zone) depth using optical suspended solids measuring technology. The system is ideal for continuous measurement of industrial and municipal wastewater sludge, sludge settlement monitoring, and control of return activated sludge (RAS) and waste activated sludge (WAS). It can also serve as an early warning system for sedimentation problems and prevents sludge washout. Krohne Inc.

Rotary fan press

The Prime Rotary Fan Press® simplifies dewatering performance for sludges/slurries by using continuous pressure differential technology to meet the needs of solids handling requirements and restricted budgets. The system uses a slow rotational speed (<1 rpm), and offers semi-automated operation and a self-cleaning feature. The system is energy efficient, portable and expandable. Few mechanical parts combined with the slow revolution reduces noise and vibration, increases functionality, minimizes maintenance and improves life cycle costs. Several capacities are available to meet flow applications of all sizes. Prime Solution Inc.

Decanter centrifuge

Solid bowl decanter centrifuges play a decisive role in improving water and wastewater treatment facility operation. High g-force and efficient drive systems help achieve the best separation efficiency. Flottweg SE has developed a new environmental decanter centrifuge, the Model C7E. It can dewater or thicken up to 700 gpm of water or wastewater sludge. This high performance decanter centrifuge is designed to provide a constant cake dryness which is important for both thickening and dewatering, regardless if the sludge is to be composted, incinerated, dried, or land-filled.

Mixer systems

Combining the Chemineer® Model 20 HT/GT mixer with the Chemineer RL-3™ impeller creates the ideal mixer for wastewater treatment plant applications. The high-efficiency gearbox of the Model 20 and the unique characteristics of the RL-3 impeller work together to reduce downtime and maintenance costs, increase performance and extend the service life of the agitator. The ragless impeller is designed to prevent fibrous material build-up on the rotating impeller of the agitator. The mixers incorporate a modular design package that reduces the number of replacement parts that need to be carried in inventory by the customer. The wide range of speeds available provides improved process control and greater application versatility. Chemineer

Rotary drum thickener

Kusters Water / WasteTech offers a complete line of rotary drum thickeners for sludge thickening. As the drum rotates, fluids pass through the perforations in the drum and fall into the water collection trough underneath the drum and are then discharged. Solids are retained and thickened within the drum and dewatered as they move to the elevated end of the drum by the internal screw auger. Kusters

Close-coupled pumps

The Moyno® 2000 Model WA and WB close-coupled pumps are specifically designed for lower pressure, lower flow applications that do not require the full features and benefits of the Moyno 2000 G1 pump. They are ideal for municipal and industrial applications that require the transfer of highly viscous fluids and solids where a close coupled configuration is preferred, but the robustness of a gear joint is desired. Bearings are integral to the adapter housing that supports the radial thrust loads at the rotor/stator. The pumps feature standard size / keyed gear reducer shaft; sealed, gear-type universal joint drive train; and optimized rotor/stator pumping element geometry. Moyno

Lime, sludge mixer

Sodimate's MBV lime & sludge mixer has a stainless steel construction ideal for many harsh industrial applications. Compact in its design, the mixer features orientable paddle blades that allow efficient mixing of lime and dewatered sludge coming from dehydration systems. It is possible to combine the mixer with sludge conveyors, sludge pumps, and lime feed systems for an effective sludge stabilization process (Class B). The MBV can mix from 0.5 up to 15 tons/hr of dewatered sludge and comes in various sizes. Sodimate


GridBee GF electric mixers can displace 30 to 50 horsepower of aeration run-time, improve regulatory compliance and control odors. Applications include activated sludge system basins, lagoon systems, and water re-use ponds in municipal and industrial wastewater. Four models are available, providing a choice of single- or three-phase power and a choice of intake designs and mixing capacity. Medora

Sludge tanks

Featuring six-foot-high walls, modular, heavy-duty sludge tanks from ModuTank are available in various modular capacities from 50,000 to 2,000,000 gallons and higher. They are designed for rapid bolt-together assembly from galvanized panels and are anchored with support frames on concrete aprons, or on free-standing steel footing plates. No special construction skills are required for assembly. A full range of membrane liners assures compatibility with virtually all qualities of sludge and wastewater. Optional fittings for piping, as well as floating covers can be specified. ModuTank

High-Pressure AODD Pump

Wilden® has announced the availability of its new HX400S High-Pressure Air-Operated Double-Diaphragm (AODD) Pump, which has been designed for use in applications that require the transfer of viscous, solid-laden slurries at high discharge pressures. Rather than relying on external boosters or amplifiers, one of the pump's liquid chambers is used as an amplification chamber. This allows the pump to generate a 2:1 ratio of discharge fluid pressure to air inlet pressure, resulting in the ability to achieve a discharge fluid pressure of up to 250 psig. Pump Solutions

Solids separation

Salsnes Filter manufactures solids separation technologies for municipal and industrial applications. Solids separation, sludge thickening and dewatering - three critical water treatment processes - are performed within one compact, automated unit. Within a very small footprint, 40-80% TSS and 20-35% BOD are removed and drier sludge (20-30% DM) is produced. The system can augment, enhance or completely replace conventional primary treatment, making it ideal for plant upgrades/expansions. Salsnes

Valve systems

Onyx pinch valves are ideal for on/off and throttling applications including raw sewerage (equalization basin flow), sludge (centrifuge feed) and lime slurry (pH control). The company's Isolator Rings are a convenient way to reliably measure pressure on sewerage, slurries and other hard-to-handle fluids. They are guaranteed to never clog or plug and are compatible with a wide array of gauges, switches, and transmitters. Onyx Valve

Inclined screw press

The Huber Technology RoS3Q Inclined Screw Press provides high performance sludge dewatering in a compact entirely enclosed machine. The press requires minimal operator attendance. It has a simple, energy efficient, slow rotational design. Huber also offers the Strainpress® Inline Sludge Screen, designed to screen sludge in pressurized lines, increasing the operating reliability of downstream sludge treatment systems. It is manufactured of stainless steel. Huber Technology

Filter presses

Toro Equipment's Draco filter presses are used to separate solids from liquids in a wide range of applications. The sludge is pumped into a series of filter chambers fitted with a permeable filter cloth on both sides. While the liquid is forced out of the sides, the filter clothes retain the solid components, leaving a filter cake deposited inside the chambers. As the chambers become full of solids, the pressure rises and it becomes progressively more difficult to continue pumping in more of the sludge. Toro Equipment
