What Is Water Turbidity?

Posted by Anthony DeLoach, President on Mar 18, 2022 1:05:00 PM

Water turbidity refers to how transparent or translucent the water is when examining or testing it for any given use.

Water turbidity can impact food and beverage, municipal, industrial, and aquaculture operations. Turbidity is caused by suspended or dissolved particles in the water that scatter light which causes the water to appear cloudy or even murky.

Different types of particles can cause turbidity, and they include sediments such as silts and clay, very fine inorganic or organic matter, algae or soluble colored organic compounds, and microscopic organisms. Turbidity is measured in a value referred to as NTU, which means Nephelometric Turbidity Unit. The EPA requires a turbidity level no higher than 0.3 NTU in the USA, and if a member of the partnership of safe drinking water, then the level must not exceed 0.1 NTU.

High turbidity can create habitats for other harmful elements, such as bacteria or metals, that can accumulate onto the particles. This increases the health risk for a potable water system. In aquaculture operations, increased turbidity from silts and sediments can be harmful and detrimental to marine life, so it must be removed to safe levels. For the food and beverage industry, the impact of high turbidity can be both a safety concern and a visual and noticeable quality concern because if the turbidity is high, it can alter the physical look of the final product, for example, a distillery.

Benefits of Pressure Filters for Industrial Water

Posted by Anthony DeLoach, President on Jan 4, 2022 1:00:00 PM

Industrial water systems use water filters to reduce the level of solids in water from:

  • Industrial
  • semiconductor
  • manufacturing
  • refining
  • oil and natural gas production processes

The wastewater may contain harmful chemicals to humans, plants, or animals. Three types of filters are commonly used in industrial settings: Gravity filters, pressure filters, and constructed wetlands. Pressure filters have two variations: multimedia and higher-pressure micron or cartridge filters. Constructed wetlands or natural filters are not often utilized in industrial processes. Based on the requirements to obtain environmental permits and safeguard the ecosystem.

Pressure Filters

Posted by Matthew C. Mossman P.E. on Dec 3, 2021 1:00:00 PM

In water treatment, it is often required to remove small particulate matter from the raw water. One of the most cost-effective ways to accomplish this is with a pressure filter. Sometimes referred to as “sand filters,” a pressure filter consists of a rigid filter vessel capable of withstanding internal pressure, combined with pipework to distribute and collect water and one or multiple types of filter media. Pressure filters, commonly used in municipal water systems, industrial facilities, residential well water systems, and swimming pools. Typical pressure filter construction is shown below:

At the top of the filter vessel, a distributor is used to break up and distribute the water flow so that there are no concentrated flow jets that stir up the media bed. Inflow distributors are usually oriented to direct flow at the top of the vessel to disperse the flow further. Below the distributor is the primary filter bed. The filter bed contains fine-grained media, most often sand, including crushed anthracite coal, activated charcoal, garnet, or other granular bulk products. The media bed is the thickest layer in the filter vessel and is the region that does the actual filtering of the water or other fluid. Below the media bed will be one or more support layers. These will usually be larger-sized gravel that is chosen to support the filter bed while allowing high flow through the support layer and into the outflow header. The outflow header can take several forms but is often composed of a large central pipe with multiple smaller pipes or “laterals” attached. The laterals are slotted or perforated. This allows the pressurized water to flow into the laterals and out through the outflow header into the downstream components of the water treatment system.

What Makes DeLoach Industries Unique?

Posted by Anthony DeLoach, President on Jul 20, 2017 3:43:33 PM

DeLoach Industries Inc. has been serving the municipal, industrial, and food and beverage industries since 1959.

DeLoach Industries specializes in the design, manufacturing, operations & maintenance of water treatment, wastewater treatment, odor control, and pisciculture/aqua farming systems.

What makes DeLoach Industries Inc. unique is that, as an original equipment manufacturer, we have extensive knowledge and we understand how to engineer, design and manufacture the equipment you need. We are different from traditional fabrication shops in that they will typically build something specific to your drawing but if there is a problem they may not understand the process involved or even how to correct the problem.

We serve each customer on a project by project basis to fully understand your needs. We offer full in house engineering and CAD design support services, manufacturing services including operation & maintenance support, and field services including annual service contracts on all DeLoach and other brand water treatment equipment.
