By Luke Wonnell Lime scale can be a serious menace to domestic hot water systems. As lime scale builds up in your system, it will restrict flow through piping, it will reduce the operating efficiency of water heaters, and it can most certainly bring your hot water system to its knees if left unchecked. For […]
Updated October 22, 2024 Protect your drain and sewer lines from acidic damage using condensate neutralizers. If your building operates a high efficiency condensing boiler, hot water heater, or furnace, you will likely have acidic condensate running through your drain lines. Left unchecked, this can damage pipes, leading to costly repairs and even code violations! […]
Despite the fact that we have just had our fourth Nor’easter in the last three weeks, the time to change you’re HVAC systems from heating to cooling is close at hand. How you perform the winter layup of the heating system or the startup of cooling system can have a dramatic effect on how your […]
Sodium zeolite softener systems consist of a softener tank, valving and a means of transporting brine (salt solution) to the softener tank. The tank includes a service and rinse water inlet distributor, freeboard or the headspace from the top of the resin bed to the top of the vertical wall of the tank, a regenerant distributor, a […]
Softener Operation A sodium zeolite softener operates through two basis cycles: the service cycle, which produces soft water, and the regeneration cycle, which restores the exhausted resin to capacity. During the service cycle, raw water enters the softener through the inlet distributor, flows through the resin bed, is collected by the underdrain system and then […]
Principles of Zeolite Softening Sodium zeolite softeners use exchange resins made of polystyrene. These resins have sodium ions loosely attached and will readily give up sodium for more desirable ions such as calcium and magnesium. This exchange is only for cations (positively charged ions). This is why sodium zeolite resin is referred to as a cation […]
Softener Application The potential for scale and deposit buildup exists in every raw water supply. The ability of the sodium zeolite softener to reduce this potential effectively and economically makes this an ideal pretreatment for boiler feedwater and many types of chemical process waters. Compared to other softening methods, sodium zeolite units offer many advantages: […]
Good water softener operation is often a key factor in efficient boiler system performance. In its simplest terms, softening is the removal of naturally occurring scale-forming ions that are present in all water irrespective of its source. Although we take it for granted, the operation of a water softener is really a remarkable phenomenon. As […]
One of the key objectives of effective cooling water management is to prevent the precipitation of scale-forming minerals onto heat transfer surfaces. Scaling potential is highest at the hottest metal surfaces, and where the transfer of heat occurs from a process into the cooling water “ across plate/frame or shell and tube exchangers. However, it […]
Keep the Water Flowing. This statement represents one of those basic rules of thumb in managing any water system. Lack of flow can lead to wide-spread system problems with microbial fouling, corrosion and even fouling from sediment. Without flow and turbulence, water systems will accumulate dissolved gases, suspended sediment will separate from bulk waters, and […]
