    Industrial Solution for pulp & paper

    Stringent regulations all over the world, including the new Boiler MACT ruling, are being enforced on new and existing air pollution control systems. Many of the existing scrubbers are having a more difficult time meeting performance criteria. Macrotek has the innovative solutions to retrofit existing systems or replace with new systems to meet and exceed new targets.

  • Membrane filtration systems for reduction of BOD/COD

    Reverse Osmosis Polishers can concentrate BOD/COD from evaporator condensate and RO permeate streams to reduce waste water. Polished water can also be re-used in plant for boiler water make-up and CIP systems. In Dairy Industry applications, `polishing` of these process water streams aids in the production of Class I water for re-use from dairy products as defined and regulated under Food & Drug Administration rules. Water produced with this technique is also very soft, generally resulting in lower cleaning chemical consumption.

  • Gas detection analyzers for pulp & paper mills

    Flammable non-condensible gases (NCG’s) are byproducts of the wood pulping process. Health and pollution regulations prohibit the release of these gases into the atmosphere. They are usually eliminated by passing them through an incinerator or by using them as fuel in the burner of a boiler or kiln. The incinerator, boiler or kiln however can be damaged by NCG’s which have built up explosive levels. Pulp mills require the use of our PrevEx Flammability Analyzers to monitor the NCG stream and detect and divert these dangerous concentrations before they can cause damage and shut down the mill. The PrevEx analyzers accurately measure the total concentration of flammable gases present in the NCG sample. Their high sampling speed dramatically improves response time—an important factor in pulp mill applications.

    Roper’s Restaurant, a cowboy themed restaurant in Albuquerque, New Mexico has replaced its water softener with the computerized, electronic, water-conditioner Scalewatcher from Scalewatcher North America. By installing Scalewatcher, the restaurant has avoided paying the $500 quoted for replacement media for its old water softener and also saved hundreds of dollars a year in salt and water thereby providing Roper’s with a short-term payback on the unit. Roper’s Restaurant, part of Outwest Eateries LLC dba, is located in a hard water area. This necessitated Bryce Chant, owner of Roper’s Restaurant using a water softener to prevent scale formation in the kitchen. “When I was given the price to repair our old water softener, I decided to install the Scalewatcher from Advance Plumbing”, said Bryce Chant of Roper’s Restaurant. We have had great success with it. Even though we had a water softener we still had hard water scale and a white ‘film’ in the dishwasher. Now with Scalewatcher that scale and ‘film’ has disappeared.” The average restaurant consumes 5,800 gallons of water daily, with 50% being used in the kitchen. If not properly treated, hard water can drain a restaurant’s bottom line due to the early renewal of capital equipment such as water heaters, boilers, coffee makers, dishwashers, steamers and other water-fed equipment. Hard water contains calcium carbonate that adheres to heating elements and the internal surfaces causing scale buildup that impairs efficiency. The limescale that deposits on the heating element will, if untreated, reduces efficiency, induces corrosion of the element and ultimately lead to appliance failure. In addition in restaurants, hard water also necessitates the use of additional detergents. In fact, for every additional grain of hard water, detergent use increases by between 2% and 4% per 1,000 gallons of water used. Many restaurants, like Roper’s use a water softener to reduce limescale. However, water softeners use copious amounts of both water and salt, which are expensive to buy and salt is also bulky to store. In addition, in many States now, including Southern California, municipalities and water departments are severely limiting, and in some cases prohibiting, the use of salt-regenerating water softeners due to concern regarding the increased levels of salt in ground water. The award-winning Scalewatcher system not only helps restaurants meet these regulations by minimizing salt usage but also saves money on salt purchase and has the additional benefit of removing scale from water-fed equipment. The environmentally friendly Scalewatcher provides a permanent solution to hard water problems without the need of chemicals, salt or maintenance. It works by producing a varying electronically applied force field, induced by a coil wrapped around the outside of the pipework, which keeps the minerals in suspension and thus prevents limescale forming. The water’s increased solubility enables it to dissolve existing scale, which is gradually washed away. “We are saving money each month because we do not have to purchase salt for the water softener and we are not dumping salt filled water down the drain because there is no brine process with Scalewatcher”, said Bryce Chant. “Living in New Mexico with our drought situation, I hated knowing all that water was being wasted. Scalewatcher is a truly ‘green’ technology that we are happy we have implemented”. Roper’s Restaurant has been so impressed with the Scalewatcher technology that the managers have bought units for their homes and have recommended it to family and friends. Scalewatcher models are based on continuous research and over 20 years experience and expertise as market leaders in electronic scale control with countless units sold worldwide. The patented Scalewatcher systems start at $248.00 USD and are capable of treating pipe sizes from one to 120 inches. All Scalewatcher systems come with a full performance guarantee and include free shipping throughout North America.
