The invention relates to a high efficiency water treatment flocculant for drinking water and water treatment comprising a metal cation flocculant which is characterized in that the high efficiency water treatment flocculant also comprises a high efficiency adsorption component and an assistant medicament to be remixed, inwhich the weight ratio is: the high efficiency adsorption component 5-15%, the metal cation flocculant 50-85%, the assistant medicament 5-15%. The obvious characteristics of the invention are that each component can play the advantages of high intensity of the flocs of the inorganic flocculant and large flocs of the polymeric flocculant, overcomes the drawback of small flocs of the inorganic flocculant and low intensity of the flocs of the organic flocculant. The existence of the high adsorption component plays the action of adsorption of the organic compounds and heavy metal ion which are difficult to flocculat and precipitate, also plays the role of aid-coagulation, decoloration and deflavour. Thus the flocculant of the invention has advantages of good coagulation effect, large alum blossom, rapid settling velocity, good effluent quality and few dosage or the like.

A method and apparatus is provided for consumers to receive the recent settlement histories of their creditors in a web-hosted application that drives the settlement process, so they can use this insider knowledge to settle their debts for cents-on-the-dollar. One embodiment provides a computer assisted tool that tells consumers what their creditors take to settle debts for cents-on-the-dollar, and equips consumers to conduct the settlement process using a turn-key, web-hosted application; or alternatively provides a full-service embodiment that allows consumers to get immediate relief from collectors and be debt free in a matter of months rather than decades. The invention thus provides debtors with at least two principal competitive advantages: it provides debtors with knowledge in advance concerning how much credit card companies may take to settle their debts in view of their financial hardships; and it provides consumers with a turn-key method to settle their debts at discounts equivalent to those that professional negotiators could achieve.

The present invention provides a power regulation system and method with high speed signal settling capabilities for providing rapid active transient response to a microelectronic device. An active transient response system includes a power supply configured to receive external and/or internal signals indicating the occurrence of transient load conditions and to respond to the transient load conditions based on one or more of these signals. The system may further include a transient suppressor configured for early detection of transients, assisting in transient suppression, and early signaling of transient activity to the power supply.

The system provides rapid recovery to steady state operation from the active transient response mode by using a digital compensator to quickly modifying the duty cycle and provide a voltage offset proportional to the transient microprocessor load step. Recovery is further improved by current rephasing techniques.

A method for minimizing the amount of metal crosslinked viscosifier necessary for treating a wellbore with proppant or gravel is given. The method includes using fibers to aid in transporting, suspending and placing proppant or gravel in viscous carrier fluids otherwise having insufficient viscosity to prevent particulate settling. Fibers are given that have properties optimized for proppant transport but degrade after the treatment into degradation products that do not precipitate in the presence of ions in the water such as calcium and magnesium. Crosslinked polymer carrier fluids are identified that are not damaged by contaminants present in the fibers or by degradation products released by premature degradation of the fibers.
