Electrochemically activated (ECA) water is being extensively studied and considered as an alternative to chlorine for disinfection. Some researchers claim that ECA is by and large a chlorine solution, while others claim the presence of reactive oxygen species such as ozone and hydroxyl radicals in addition to chlorine. This study compares sodium hypochlorite (NaOCl) and ECA in terms of disinfection efficacy, trihalomethanes (THMs) formation, stability and composition. The studies were carried out under different process conditions (pH 5, 7 and 9, disinfectant concentrations of 2–5 mg/L and dissolved organic carbon (DOC) concentration of 2–4 mg/L). The results indicated that in the presence of low DOC (<2 mg/L) ECA showed better disinfection efficacy for Escherichia coli inactivation, formed lower THM and had better stability compared with NaOCl at both pH 5 and 7. Stability studies of stock solutions showed that over a period of 30 days, ECA decayed by only 5% while NaOCl decayed by 37.5% at temperatures of 4 °C. In a fresh ECA of 200 mg/L chlorine, about 5.3 mg/L ozone and 36.9 mg/L ClO2 were detected. The study demonstrates that ECA could be a suitable alternative to NaOCl where decentralized production and use are required.

 INSTRUCTIONS FOR USE
1. A clean, representative sample of the supporting water should be obtained by means of a sampling can or other suitably designed sampling apparatus. A sample of at least 1 liter will help to ensure that the temperature and density do not change unduly between the collection of the sample and taking of the readings. The depth of water in the container must be sufficient to allow at least 25mm clearance between the bottom of the hydrometer and the bottom of the hydrometer and the bottom of the container. The internal diameter of the container or jar should be at least 50 mm.
2. The number of samples to be taken, also at which depths and at which positions outside the vessel they should be taken, may be important according to the circumstances.
3. Readings may be taken by lowering the hydrometer into a suitably shaped sampling apparatus or by transferring the water to a suitable glass test jar. If a metal or other non-transparent container is used for taking readings, ensure that it is full to the brim. If a glass test jar is used, it should preferably be rinsed first, so as to avoid undue temperature changes. The container or test jar should be shielded from draughts, which may affect the readings.
4. The reading must be taken in the sampling apparatus or glass test jar as rapidly as possible Undue delay in taking the reading could result in temperature changes leading to inaccurate results. In case of doubt, a repeat sample should be taken in order to verify the first observation
5. Ensure that the stem of the hydrometer and the surface of the water sample is free from grease and oil since the accuracy of the readings could be adversely affected
6. Hold the hydrometer vertically by the top of the stem and gently lower it into the water sample until it floats freely
7. Take the hydrometer reading where the level liquid surface meets the graduated scale.

CORRECTIONS TO HYDROMETER READING
1. For ydrometer the appropriate corrections should be applied.
2. For most Draft Survey purposes, no further corrections to the readings are needed.
Reading is most correct when the glass hydrometer is used at a temperature of 15°C. If immersed in water at temperatures higher or lower than 15°C, the instrument will expand or contract so that, for precise laboratory work, a small correction would be applicable However, for Draft Survey work, it should be noted that the ship itself will normally expand or contract according to the temperature of the water in which it is rating. The corrections required to compensate for these changes in volume are of opposite signs and tend to compensate for each other. As it is not practicable to calculate any temperature corrections for the ship, for most Draft Survey purposes no correction should be applied for the expansion or contraction of the hydrometer glass

Silica Gel Details
CAS No. : 112926-00-8
Chemical Name : Silica gel
CBNumber : CB1199389
Molecular Formula : O2Si
Formula Weight : 60.08

For proper functioning of transformer dehumidification of Silica Gel crystals & removal of dust particles from breathed air is necessary.

Moisture is removed from Silica Gel crystals by heating it inside a ventilated oven at to 150 C, until the color becomes deep blue again.

Dusts particles are filtered by the oil in the oil cup.Pressure value for air passage into the breather are: 0.003 Kg/cm inlet or 0.005 Kg/cm outlet.

Criteria for Selecting Silica Gel Breather :
Keeping in view the above functions of Silica Gel Breather the main criteria for selecting the breather becomes,

• Gel changes color from deep blue to pinkish white as it absorbs moisture. By reheating, the Gel becomes free from moisture & hence transformer always breathe in dry air. Visibility of Gel color is very important to decide when to reheat the Gel.
• Oil in the oil cup allows dust particles of air to settle in the oil. By changing the oil & cleaning the oil cup air becomes free from dust particles. Visibility of oil level & dust particle in the oil cup is very important to decide when to change the oil.
• Transformer should breath from breathing holes (provided in breather) only. If air enters through any other portion of the breather except breathing holes it is called leakage of air.
• Leakage of air will lead to entrance of air with moisture & particles in the transformer, which ultimately may lead to formation of spark, and short circuit in the transformer.

Breathing Process of Transformer :
Breathing is the process where the transformer Breather-In or Breather our the air from its body due to thermal contraction & expansion of oil mass. When the transformer is loaded or unloaded, the oil temperature inside the transformer tank rises or falls accordingly the air pressure inside the tank changes by either breathing in or breathing out the air. This phenomenon is called "Breathing" of the transformer. Now, the air which is being breathed in contains either dust particles and/or humidity that change the dielectric strength of the oil. For proper functioning of transformer, it is absolutely necessary that dielectric strength of transformer oil remains unimpaired. Hence, it is necessary that, the air entering into the transformer is free from moisture & dust particles.
