Booneville, Indiana has selected Hydro International’s Storm King with Swirl Cleanse to provide treatment at their two CSO sites. Midwestern Engineers announced that a Notice to Proceed for construction has been given to Peyronnin Construction Company for the North and South CSO sites in Booneville. Operation is scheduled to begin by the end of 2011.
Each site will comprise of a 44-ft diameter Storm King that will receive flows from existing CSO basin and provide Primary Treatment screenings down to 4mm; and disinfection with sodium hypo-chlorite to meet IDEM standards. Each unit is designed to handle a peak flow of 42-mgd with a hydraulic retention time of 9 minutes at peak flow.
These will be the first installation of this technology in Indiana. Hydro International has fifteen similar facilities throughout the U.S. with the longest in operation since 1945.
New Monster Manhole
Dig a hole and YOU’RE DONE!
The new pre-built Muffin Monster Manhole from JWC Environmental is a sewer system solution for cities, nursing homes, hospitals, jails and other institutions facing a stubborn problem – rags, trash and debris clogging sewer lines and pump stations.

How Low Can You Go?
The Smallberry Low-Profile Cascade Aerator (LPCA) manufactured by Jim Myers and Sons is a free flowing, efficient, packaged, channel type aeration device that can be installed in new or existing treatment facilities at an economical cost. The purpose of this unit is for raising the dissolved oxygen (DO) concentration level at the outfall of the WWTP. Contrary to prior cascade designs, where water falls steeply from step to step, requiring great depth for installation, the LPCA utilizes slopes of less than 5.5 degrees. Each channel is fitted with a series of turbulence-control aeration baffles and air-induction plates. The refined, small air bubbles and mixing created by natural gravitational forces through controlled velocity, pressure differentials, baffles, air induction plates and controlled head make the LPCA the most efficient and economical method for post aeration.

This handheld unit is a portable optical meter designed to measure sludge blanket depth and suspended solids in clarifiers, thickeners, aeration basins, etc. in water and wastewater plants, as well in other facilities. It is possible to display measured values as text or as a graphic image of the sludge profile. Two different alarm levels for the sludge blanket may be set to indicate fluff and sludge blanket levels. These may be displayed next to the graphic sludge profile. The Blanket Tracker is able to store up to 250 measurements as a graphic profile, each with information about time, date, location, that may be named by the user (maximum 10 characters e.g. Clarifier 2; Thickener 5, etc). Each profile also contains data about blanket and fluff depths that applied for the specific measurement. The Blanket Tracker is delivered in a practical briefcase. Battery life is approximately 2-3 years at normal use.
