Enter course description here.Industrial Water TreatmentIn 1958, the Robert B. Hill Co got started as a Permutit Dealer. Ever since then we have specialized in designing custom industrial water treatment equipment built for our client's needs. Our industrial department can assist from design and development to delivery and start-up of your project.

Typically, our industrial systems start at 100 GPM up to any flow rate required for your application. Our industrial capabilities include: Filtration, Water Softeners, Reverse Osmosis Systems, Deionization (DI), Dealkalizers, Arsenic Removal, Radium Removal, Uranium Removal, and many other applications.

Industrial Water FiltrationA major component of any water treatment system is filtration. We design and manufacture filtration that can treat any type of water. One common method of filtration is for TSS, iron, and manganese. Common medias that are used for filtration are sand, multi-media (which is layers of various medias), greensand, greensand plus, and birm. When designing filtration systems, several factors must be considered:

Elements being removedLevels of the elements being removedpH levelsRequired flow rateThe velocity of bed surface area in square foot per minuteRequired retention timeAnother common filtration application is the use of carbon. Carbon filtration can be used for the removal of chlorine, benzene, radon, solvents trihalomethane compounds, and volatile organic compounds (VOCs). There are also specialty carbons that remove many other compounds from the water.

Industrial Water SofteningDue to high levels of calcium and magnesium, many types of equipment fail to work properly or efficiently, which can lead to an increase in energy costs and/or complete failure of the equipment. Many plants use water softeners for boiler feed, cooling towers, entire water supply and various types of process water.

When using water softeners for boiler feed, there are several commons factors that go into the design:

Boiler HPCondensate returnOperating pressureWater hardnessBoiler feed typically consists of alternating water softeners to allow a continuous feed of soft water. Because of the efficiency of boilers, capacity and not flow rate is the main issue in designing the water softener system. The higher the operating pressure of the boiler, the more stringent the water quality requirements will be.

Cooling towers are another common application for industrial water softeners. Cooling towers can operate much more efficiently with softened water. This can help to realize a drastic reduction in maintenance, chemical feed quantity, and the volume of water required for operation.

Things to consider when designing a water softener for a cooling tower are:

TonnageThe current number of cycles before blowdownSize of feed line to the cooling towerWater hardnessFlow rate and capacity are major concerns when designing a softening system for a cooling tower. A thorough understating of daily water usage and required flow rates are critical.

Most customers decide that using water softeners for their entire plant feed water is necessary. Due to high hardness levels the majority of the time, this is the only option as it is usually the most cost-effective and protects the entire plant from complications and damage that scale can cause.
