  • A New, Real Technology for Solids Dewatering

    Over the past decade, there have been few significant improvements to the performance in sludge dewatering technologies. Most improvements, other than process optimizations from the polymer industry, have been minor adaptations to the various dewatering technologies such as adding additional pressure rollers or modifying the diameters of pressure rollers on a belt filter press. The adoption of ...

  • Wastewater-Solids Dewatering Odor Control - Case Study

    Background The Milan Wastewater Treatment Plant, located just south of Moline, Illinois, is a 1.7 MGD (6,434 m3/day) activated sludge facility with an average wastewater flow of 700,000 gpd to 800,000 gpd. This facility dewaters primary sludge using a belt filter press (Figure 1). The press operates an average of three times per month, 8 hours per day at a pump rate of 100 gpm. The ...

  • The Importance of Dewatering

    With spring comes two things: the onset of construction season for most of our country and rain- lots and lots of rain. The unpredictability of storms and the amount of rainfall is all a guessing game.  Jobsites flood, work stalls and projects get delayed. Rain makes it hard to keep dry and on-schedule. What’s the solution? Dewatering is a technique used to control ...

  • Oil Field Sludge Dewatering

    An oil field contract dewatering company was unable to dewater the oily/water/solids from several oil field storage tanks using conventional coagulants/flocculants. The swings in solids loading and oil content made it very difficult to control the correct dosage rate as conventional chemistry has a very tight tolerance to maintain a dewaterable floc. The result was an ongoing blinding problem for ...

  • Case study: Petroleum coke dewatering

    Challenge Petroleum coke (often abbreviated Pet coke or petcoke) is a carbonaceous solid derived from oil refinery coker units or other cracking processes. Petroleum coke is typically created in a drum and solidifies. Once the products cooling cycle is complete, the coke is hydraulically cut from the drum and transported to a pad or pit, where the water then separates from the coke. It ...
