Improve Effluent Quality

Sand and grit removal is the most inexpensive repair that can be made to a wastewater treatment facility to achieve greater effluent efficiency. The sand and grit in your wastewater plant does not have to be 2-3 feet deep covering the entire bottom of the tank to hinder the process. 1-2 feet along with rag buildup around the diffuser area is more than enough to have a hydraulic impact on the plant’s efficiency. This will require increased air and blower time which significantly increases electrical consumption.

100% Efficiency & Capacity

A properly operating plant operates as originally designed with 100% optimum effluent results. Removing sand and grit, restores plant volume, increase retention time, and increases the life of filtering systems. Removing grit decreases the chemical needs such as polymers and alums and restores tank flow and treatment to its original design. Removing sand restores the air transfer system (DO Transfer) to maximum design efficiency. NOTE: 1 yd3 of sand displaces 202 gallons of volume.

Longer Equipment Life

Sand, grit and rags are the leading causes of premature equipment failure for blowers, motors, belts, pumps, mixers and diffusers. By removing the sand and grit, you will assure your equipment has a longer life and less down time.

Tax Deductible Maintenance Expense

Sand removal is a necessary, but sometimes overlooked, part of maintaining a wastewater treatment facility. A clean and properly operating plant assures future generations a greater percentage of clean water.

Q: How Does Sand Get Into Your Plant?

A: Wind blows grit directly into a plant, sand washed off in the shower after a long day at the beach, or infiltration in the collection system all bring massive amounts of grit into your WWTP every day. Florida’s fine sugar sand will sneak in no matter how hard you try to stop it. Sand builds up unnoticed at the bottom of tanks until eventually a plant is completely overwhelmed by it. We love our Florida beaches and the feel of sugar sand between our toes, but you know what really doesn’t like all that sand – Florida’s wastewater treatment plants.

Q: What Are the Impacts of Sand for WWTPs?

A: Sand causes premature equipment failure all over wastewater treatment plants. It chokes pipes, and fills processes and channels – it is a literal maintenance nightmare. It decreases capacity all over the plant, increases energy costs of blowers and mixers, and tears up expensive pumps. As it deposits in plants over time it becomes increasingly difficult (and expensive) to meet effluent discharge requirements. Sand in a WWTP is the number one cause of low Dissolved Oxygen (DO). Low DO not only causes odor by starving and killing off the good bacteria needed to break down and process waste, it’s also a breeding ground for filamentous bacteria that can devastate a plant’s operation. Removing sand from wastewater tanks is the most cost-effective way that a treatment plant can preserve capacity, reduce O&M costs, and improve efficiency.Settled Solids Management Can Stop This
