ProAct Services Corp. is currently providing water treatment for removing solids and silts from storm-water runoff collected during the billion-dollar Montreign Casino Resort Project, which started in August 2015. ProAct’s proprietary Chemical Treatment Systems (CTS) and Solids Removal Systems (SRS) were designed specifically to remove fine silts and solids in accordance with the State of New York erosion control requirements for the project.
The Montreign Casino Resort site, also known as Adelaar, will be a four-season destination resort under development near the town of Thompson in Sullivan County, New York. The casino itself will span some 80,000 square feet and feature 61 table games and 2,150 slot machines.
The four-star, four-diamond hotel is expected to offer nearly 400 luxury rooms, many diverse dining and entertainment options, conference and meeting spaces, and other resort amenities. The 18-story facility is designed to blend into the natural beauty of the Catskills, while still offering a striking, modern visage. The resort will feature an indoor water park as well as an entertainment village.
During construction, whenever the earth is disturbed, storm-water must be collected in retention basins. The sediment and solids do not settle out on their own within the basins. This is where ProAct comes in. Under Part 2.12 of Erosion and Sedimentation Controls Section 31 25 13, the solids, sediment, and silt must be removed before the water is released from the pond. ProAct designed and constructed the CTS and SRS specifically to target the silt, sediment, and solids at the Montreign Resort site.
The CTS systems work by injecting an environmentally friendly dual-polymer system into the influent line. Static mixers after each chemical injection help blend the water and polymers before the water enters the weir tanks. All flocculated and filtered sediment collected by the CTS can be reused as fill at other areas of the site. The polymers biodegrade into a simple sugar and are safe for the environment and wildlife.
ProAct’s uniquely designed and patented enclosed SRS treatment trailers are also used to treat the retention basin water. The SRS treatment systems provide treatment for TSS (total suspended solids), turbidity and pH. These systems operate at up to 400 gallons per minute, depending on the flow rate needed to provide the most effective polymer chemistry treatment.
The SRS systems were chosen for their highly sophisticated automation and (being fully contained and heated) their ability to operate in all weather conditions. Automation allows for easier control in maintaining an optimal treatment process and reduces overall costs on labor, oversight and chemical use. The SRSs have in-line metering to monitor the influent process water for turbidity and pH. Two polymer feed systems are automatically metered for pH control and superior floc formation.
The suspended solids are removed using geotextile tubes, sand filters, and bag filters. A PLC (programmable logic controller) monitors the final effluent quality for pH and turbidity. If these parameters fall outside the discharge permit levels, the discharge flow is automatically diverted back to the beginning stage of the treatment process and will continue in recirculation mode until the discharge is within spec. This ensures compliance to avoid costly discharge violations.
ProAct Services is the sole provider of water treatment during this large project and has successfully treated over 50 million gallons of water since its start. The project is expected to be completed in 2018.
