Discharge from a textile plant in Monrocvillc. Ala., paid 90 percent of operating costs for the Hudson Branch Wastewater Treatment Plant. The 2 mgd (design) activated sludge extended aeration facility ran two 12^ lip propeller-type aerators la its 11-lbot-deep wastewater pond. Power usage averaged $12,500 per month,

When the textile plant dosed in 2009. Hudson Braridi installed a baffle curtain in the pond, cutting its capacity in half. With Hows averaging 250.00O gpd. operators cy

Problem

The town of Monroeville, Ala., faced aeration and mixing issues, sludge buildup in one of its wastewater lagoons, and power bills of S12,500 per month after a major employer relocated its garment manufacturing facility. The company had generated about 90 percent of the wastewater entering the lagoon, and its fees covered 90 percent of the operation and maintenance cost, which included $1,500 per month for aerator maintenance. The lagoon was 80 percent full

Problem

The city of Taylorville (Illinois) Street/Sewer Department faced issues with hydrogen sulfide in three lift stations and with biofilms further downstream in the delivery piping to the wastewater treatment plant. The discharge manhole H2S readings were over 700 ppm, and local residents complained of odors.

Solution

The city purchased three Little John Digesters from D02E Wastewater Treatment. After the first month of ru

A constant problem in many wastewater collection systems is the formation of hydrogen sulfide (H2S) in the lift stations as well as from biofilms further downstream in the delivery piping to the wastewater treatment plant. The DO2E representatives suggested that we use their proprietary Digesters equipped with an ozone (O3) capability to remove this problem from our system.

Hydrogen sulfide formation is a real nightmare to deal with as it is quite toxic, smells absolutely horrible,

Scenario:

F.O.G. (Fats, Oils & Grease) deposits in both grease traps and lift stations accumulate within a short period of time. Their removal requires high-pressure Vac-Trucks and hazardous chemicals to break down and remove the unwanted build-up.

Problem:

Several problems occurring because of grease accumulation are:
1.) Clogged sewer lines
2.) Sanitary sewer overflows (SSO`s)
3.) Raised hydrogen sulfide l

Abstract:

An introduction to this DO2E technology cover s a var iety of appl i cat ions inc luding environmental remediations, polishing ponds for municipal and industrial sites, and internal usage of this technology in municipal wastewater systems. The unique advantages of these are examined at length.

As those who manage and/or operate waste treatment facilities of one sort or another, at the end of the process all are faced with that age old question – What now? How do we get rid of the finished “by-products”? We have several options among which are deep-well injection, holding and polishing ponds, or discharge into an existing body of water be it a stream, lake, or even the ocean. No matter which method we are using, all of them require us to deal with the sludge genera

Problem

The operators at the Lakes Area Sewer Authority treatment plant in Cass County, Mich., sought an efficient filtration system to meet stringent summer phosphorus limits. The city wanted a high-rate filtration system with a small footprint to fit inside a small building, with low wash water usage, easy cleaning and low maintenance cost.

Solution

Based on a successful pilot test, the operators chose the Fuzzy Filter from

Problem

The Frank E. VanLare Wastewater Treatment Facility in Rochester, N.Y., required an efficient aeration solution for its six holding basins.

Solution

Ten model NX350-C080 blowers from APG-Neuros were purchased by the county and commissioned in three phases over a nearly threeyear period. The blowers have Schneider Modicon PLCs with hardwired controls from the AER PLC with Ethernet connections as backup. Aside from the re
