The study aimed at conducting a water quantity audit in a Ghanaian beverage plant. Primary data on the daily volumes of input water from the main reservoirs of the plant, daily volumes of beverage produced and the water consumed at the 8 metered stages of the plant out of a total of 12 stages were recorded over a period of four months. Secondary data on the plant's monthly water consumption was obtained from Ghana Water Company Limited billing records for the period January 2005 to December 2009. The study revealed that, the average monthly water consumption was 9,825 m3 with a standard deviation of (±1,399) in the past five years (2005–2009). Stages with high water usage in the plant were the Syrup and Beverage Preparation stage (55%) and the Bottle Washer Equipment stage (34%). Furthermore, the plant's specific water consumption determined was 3.5 : 1 which is better than the company's target of 4 : 1. This indicates that the plant's current water use efficiency is good and therefore encouraging.
Case study - City of Montreal upgrade of Atwater and Des Baillets water treatment plants
Sidestream Venturi Injection—Basin Nozzle Manifold Contacting System. Montreal, Quebec, CanadaThe Problem: In 2001, a water quality audit revealed that two of the largest drinking water plants in the City of Montreal were out of compliance with Quebec’s latest water quality rules. In response to the audit, the city upgraded the 1,400 MLD Atwater and the 1,280 MLD Charles J. Des Baillets (Des Baillets ) Water Treatment Plants (WTPs) to comply with the water quality rules and meet the water quality...
Are you wasting the cashback potential of energy audits?
If the government offered your business £20 cashback on every £100 you spent on energy, you would probably head for the front of the queue. Yet that`s exactly the sort of money saving opportunity an energy audit can deliver. The Carbon Trust`s analysis of a sample of recent ESOS energy savings opportunities assessments showed that an average cost reduction of 20% was achievable through cost-effective energy saving measures. On an average energy spend of £1.8m, this translates into potential...
Choose Your Own Auditing Adventure
Four Approaches for a Customized Environmental Auditing Program Compliance audits are a tool commonly employed by EHS managers to evaluate the effectiveness of their programs in meeting national, regional, and local regulatory requirements. Comprehensive audits will present not only findings, but also root causes and corrective actions. Based on internal capabilities and the reality of EHS budgets, companies can decide whether external consultants will play a role in executing audit programs. When considering...
Perform Energy Audits Using Ultrasonic Flow Technology
With the rising cost of energy and escalating environmental concerns, the need for accuracy in energy consumption measurement has never been more critical. According to the US Department of Energy, the average industrial plant spends about 30% of their operating budget on energy. With so much tied up in energy costs, how do facility managers ensure their processes are running efficiently with minimal energy being wasted? The GE PT878 clamp-on ultrasonic flow meter offers a reliable and cost-effective solution....
Towards energy neutrality by optimising the activated sludge process of the WWTP Bochum-Ölbachtal
As a result of Ruhrverband's regularly performed energy audits the wastewater treatment plant (WWTP) Bochum-Ölbachtal shows substantial deficits concerning energy efficiency. Due to the energy consumption of internal recirculation, mixers and return activated sludge (RAS) pumping the existing pre-denitrification process configuration offers a specific energy consumption for biological treatment of 23 kWh (PE · a)−1. In order to optimise the energy situation and to improve the treatment efficiency, the process...
